The TCS market cap fell to about Rs 8.80 lakh crore on Wednesday, 28 Oct 2026, as the shares traded at Rs 2,430.10 on the NSE at 11:59 AM, down 2.68% from Rs 2,496.90 (my calculation of market cap from the data provider’s share count). Jio Platforms listed 21.36% above its issue price and, at about Rs 12.55 lakh crore, moved into second place, which pushed TCS out of India’s top five most valued companies.<\/em><\/p>\n

Quick Answer<\/strong><\/p>\n

The TCS market cap slipped out of India’s top five because Jio Platforms listed at Rs 1,358 and now has a market cap of about Rs 12.55 lakh crore, second only to Reliance Industries at about Rs 15.93 lakh crore, while the Nifty IT index fell about 3.5% on AI worries and job-cut news. By my calculation TCS, at about Rs 8.80 lakh crore, is now level with State Bank of India at about Rs 8.83 lakh crore, and both sit behind ICICI Bank at about Rs 9.89 lakh crore. Reliance Group’s combined value of about Rs 29.8 lakh crore has also moved ahead of the Tata Group’s Rs 25.92 lakh crore reported on 16 Oct, though the result depends on how overlaps are counted. This is educational and not a recommendation.<\/p>\n<\/p><\/div>\n

The TCS market cap has dropped out of India’s top five for the first time in decades, according to the report behind the headline, as the Jio Platforms listing reshuffled the ranking. This article shows the updated ranking, how much of the TCS market cap change is the new entrant and how much is TCS’s own fall, what is happening to TCS shares, and what the Reliance Group and Tata Group numbers do and do not mean, using prices as of 11:59 AM IST.<\/p>\n

Market caps here are my calculations: the data provider’s market cap at the previous close, scaled to the 11:59 AM price, and Jio’s from 920.9 crore listed shares. Group totals depend on which companies are counted, so I use the 16 Oct Business Today report for the Tata Group figure and note where it is stale. The ranks of TCS and SBI are within about 0.3% of each other, so the TCS market cap and SBI’s can swap places at any minute. It is educational and not advice.<\/p>\n
